Abstract

The invention provides a backlight compensation method and device and a storage medium. The method comprises the steps of acquiring a control signal used for controlling the brightness of a backlight module; determining compensation information corresponding to a specific position in the backlight module; wherein the specific position is the position where the mini LED which is displayed abnormally is located, the compensation information comprises a row compensation value corresponding to a specific row and a column compensation value corresponding to a specific column, the specific row and the specific column are the row and the column where the specific position is located respectively; and according to the compensation information corresponding to the specific position, performing stepped compensation on a plurality of rows in a first preset range of the specific row and a plurality of columns in a second preset range of the specific column to obtain control signals of the mini LEDs in each row and each column after compensation, and controlling the brightness of the backlight module according to the control signals after compensation. Therefore, the brightness uniformity of the backlight module can be improved, and the phenomenon that the brightness of a liquid crystal display screen is not uniform is improved.

Description

technical field [0001] The present invention relates to backlight compensation technology, and in particular, to a backlight compensation method, equipment and storage medium. Background technique [0002] With the development of science and technology and the continuous improvement of people's living standards, LCD screens are widely used in our daily consumer electronic products. Since the LCD screen itself does not emit light, a backlight source needs to be installed behind the LCD panel. For example, the Back Light Unit (BLU) is a kind of backlight source located behind the LCD screen. The probability of the light passing through the backlight module is used to adjust the effect of the video image. Since there are many mini LEDs in the backlight module as light sources, the brightness of the mini LEDs may be uneven. [0003] In the prior art, through the estimated backlight compensation value of a display abnormal area, the low-brightness part of the original image is ...
